BARB FOR WIRE FENCES.

SPECIFICATION forming part of Letters Patent No. 472,044, dated April 5,1892.

Application filed December 26, 1891. Serial No. 416,119. (No model.)

To alt whom it may concern.-

Be it known that I, HUGH GEARTY, a citizen of the United States,residing at Springfield, in the county of Sangamon and State ofIllinois, have invented a new and useful Improvement in Barbs for WVireFences, of which the following is a specification.

My invention relates to'improvements in the barbs used on wires forfences; and the ob ect of my improvement is to obtain asafetybarb thatwill be sufficiently severe to make the fence stock-proof and that willnot greatly 111 ure animals if they are forced over the wires. I attainthese objects by making a barb as illustrated in the accompanyingdrawings, in which Figure l is a view of the wire B, showing the methodof fastening the cross-wire O to it,

which holds the barb A in place on B. Fig.

2 is a section of the wire B, further illustratlng Fig. 1. Fig. 3 is aside view of the barb A on the wire B. Fig. 4. is a front or edge viewof the same. Fig. 5 is a section of the barb A with wire B passingthrough; and Fig. 6 1s a section of A with the wire removed, showingmore clearly the groove a Similar letters refer to similar parts throughout the several figures.

The barb A is of metal, made wheel-shaped, wlth points on its perimeter.To fasten barb A to the wire B, I make it in two parts a and a. Part ais made wedge-shaped toward the center of the barb A, also slightly toone side, and part a is made so that piece a will exactly fit into piecea. Parts Ct and a each have corresponding semicircular grooves on oneedge, so that when the pieces a and a are shpped into their relatedplaces the two grooves form a circular hole, through which a rivet dbeing driven binds piece a firmly into piece a. There are other wayswhich I use for binding the barb .A onto the wire other than this. So Ido not confine myself to this form. The barbA has a hole through itscenter slightly larger than the wire B on which it is placed, so that itmay easily revolve about wire B when fastened thereon. To confine barb Ato one position laterally on wire B and allow it to revolve freely, Iplace a groove a in the perimeter of the hole through its center, asshown in Figs. 5 and 6. Into the wire B where I want the barb A locatedI insert a bent wire 0 between the strands which compose wire B, asshown in Figsfil, 2, and 5. The ends of Wire 0 extend beyond the generalcircumference of the wire B and into the groove a in barb A where barb Ais placed on wire B.

In making barb A so that it will revolve on wire B in a planeperpendicular to wire B animals will not have their flesh torn or beseverely injured by falling on the wire or by dragging over it. Itisforthat reason I term it a safety-barb.

I use other Ways of fastening barb A onto wire B than shown, as fixing ashort wire like 0 into wire B on each side of barb A, and so do notdesire to confine myself to the method here shown.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

The combination, with the fence-wire B, of the barb A, composed of partsa and a, which fit into each other and are secured by a rivet d andhaving a groove a in the periphery of the central hole, through whichpasses the wire B, and the bent wire 0, woven into wire B, all arrangedto allow barb A to revolve freely on the wire B, substantially as andfor the purposes set forth.

HUGH GEARTY.
